OPERA-CHAIR.

Application filed February 11, 1908. Serial No. 415,330.

clare the following to be a full, clear, and

exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

My present invention relates to seating appliances, and particularly toseating appliances comprising chairs interconnected in series, such asopera chairs.

In devising the improvements, herein set forth, I have had in mind, inaddition to.

providing a seating appliance which shall be durable in construction andafford a rigid and substantial support, so to construct the same that aseries of the interconnected chairs may be adapted to varying curves andfloor inclines and adjustable to varying conditions in reference tospace, whereby to se-' cure a more perfect alinement of the chairs withreference to the aisles and economy in seating space.

A further object is to construct the chairs so that they may be shippedto the floor in as compact form as possible and so far assembled thatthe work and skill required in setting them up will be very materiallyre-- duced. Referring to the accompanying drawings, in which myinvention is fully illustrated, Figure 1 is a perspective view of theimproved seating appliance, showing three interconnected chairs; Fig. 2is a view in side elevation of one of the chairs, its near side standardbeing shown in dot and dash outline; Fig. 3 is a vertical sectional viewthrough the structure comprising the seat and back; Fig. 4 is afull-size sectional view 011 the line w w of Fig. 2, Fig. 5 is a simi*lar sectional view on the line wm of Fig. 2; Fig. 6 is a similarsectional view on the line yy of Fig. 3; Fig. 7 is a similar sectionalview on the line z-z in Fig. 3; and, Fig. 8 is a sectional viewillustrating a modification.

In said drawings a designates the side standards each having an arm-restb and a Suitable base 6 of such character that each side standard, whenproperly screwed to the floor, will be adapted to resist any forward andbackward tilting action; in practice, where the chairs adjoin eachother, as in a .row of chairs, it will be understood that each sidestandard serves for two chairs.

(Z designates the back and e the seat. -According to the presentconstruction, and by preference, the back and seat are pivotallyconnected together so as practically to constitute one structure, theside standards being separate, and suitable couplings are provided forconnecting said structure with the side standards so that the sidestandards may be first set up on the floor with reference to economizingthe space available for a row of chairs between aisles and so that anydesirable curvature in such row may be secured. To this end, the meanswhereby the back and seat are pivotally connected together comprises thebrackets f (Figs. 2 and 3). Each bracket is formed in two parts 9 and hsuitably pivoted together at 2'. The part 9 is preferably a flat uprightcasting having on the inside the projections j to which the back may besecured, by rivets, screws or the like is, the lower projection beingformed with a stop Z against whichthe lower edge of the back may abut sothat in assembling the back with the brackets f the two brackets may beplaced in true opposition to each other with a view principally tosquarely aline the axes of the pivots t and thus prevent binding in saidpivots when the seat is raised orlowered. The part it may be of wellknown construction, comprising a flange m to which to secure the seat 6,to reinforce the seat, the parts it may be connected at the back by thebar a in a well known manner. Each part 9 is formed with two elongatedvertical slots 0 each opening, on the inside of said part, into anelongated socket p, the socket extending at both ends beyond the end ofthe slot; these are placed the one preferably near the lower end of part9 and the other preferably near the portion of part g which adjoins thearmrest 0 when the chair is assembled, the lower one being thrustsomewhat forwardly of the other with a view to bring it as near to thecenter of gravity of the chair as practicable. Through the slots 0 areslipped the curved flat studs 9 having longitudinal slots 1" and eachalso formed at one end with the pintle .9, said pintle resting in andsubstantially fitting the socket p and thus acting Specification ofLetters Patent.

as a pivot for the stud and as a stop preventing the stud from beingdrawn clear through.

the slot. The upper studs are of course assembled with the brackets 9before the back-cl,

is attached. The back, the seat and the means for pivotally connectingthem being thus 1 assembled and having the studs attached are now placedbetween the side standards,"-bolts It being passed through the sidestandards and the slots of the studs to clamp the studs afi'orded by thebolts alone the parts of the side standards against which the studs bearmaybe recessed, as at a, Figs. 4 and 5, the studs substantially snuglyfitting such recesses; as, in some instance, however, it

'might be desired that the back be capable of adjustment to variousinclines the recesses u may be omitted, (Fig. 8) thus allowing thecouplings to assume such an angle as would be required for the inclinedesired.

My construction results in a compact, substantial and simple type ofchair adapted for use as one unit of a row of chairs; each side standardbeing unitary, and the assem bled hinged backs and seats being likewiseso, these parts may be shipped to the floor;

in only two lots, so that all that is then required is to bolt the studsto the side standards. The side standards are .first set up, havingproperly spaced them with a view to' economy of the available space andto secure. their proper alinement, both as to rows of chairs and withrespect to the aisles, and

then the backs and seats secured to them in; the manner stated, thestuds, by being pivoted and curved, readily adjusting themselves .tovarying conditions of space between said standards.

Having thus fully described my invention,

what I claim as new and desire to secure by;

7 Letters Patent is:

1. The combination of the side standards, the back, the seat, and meansfor supporting 'the 'bac'k and seat on the side standards comprisinghinged brackets, one part of each bracket carrying the seat and theother part carrying the back, and said means-also comprising devices,pivotally attached to the upper and lower portions of said other partsof the brackets, for securing said brackets to the side standards,substantially as described.

' 2. The-combination of side-standards, the back and seat members, andmeans for supporting one of said members on the side standardscomprising an upper and a lower pair of studs curved laterally in asubstantially horizontalpl-ane, each stud connecting said :memberand aside standard and being pivoted in one and bearing'in its curved por- 5.tion against the other, substantially as described.

3. The combination of side-standards, the

back and seat members, and means for supn gporting one of said memberson the side standards comprismg an upper and a lower pair of studscurved laterally in a substantially horizontal :plane. arranged thelatter forward of the former, each stud connecting said memberand a sidestandard and being 7 pivoted in one and bearmg 1n itscurved portionagainst-the other, substantially asdescribe 4L. The combination of sidestandards, the 'backandseat members,.. and means for supporting one ofsaid members on the side standards comprising curved studs, each studhaving a pintle at one end and said side standard and member havingtheone a slot receiving said stud and being shorter than the pintlethereof and the curved part of the stud being securedagainst the otherof them, substantially as described.

In testimony, that I claim the foregoing, I

have hereunto set my hand this 8th day of February, 1908. V
